Claims. l

The present invention relates generally to shoe forming machines, and more particularly to a novel machine adapted to shape one-piece rear shoe quarters. A

Briey, the present invention comprises astationary electrically heated Vsupporting form of appropriate shape and a movable, molded, iiexible saddle adapted to embrace the form in a combined wrapping and clamping action, an appropriate linkage arrangement being provided to impart the desired motion to the saddle. The movement of the saddle is manually eiected through adjustable spring tension to provide a desired clamping force and a releasable latching arrangement is provided to maintain the saddle in clamping position. l

The rear quarter of a shoe is that part in the back of the shoe that passes around the heel, and, in the case of high shoes, around the ankle. Shoes generally are made with the rear quarter in two parts, the parts being out in such a way as to form an appropriate shape around the heel and ankle and then stitched together at the back. The seam thus formed is'covered by a stay attached thereover, the stay serving both to reinforce the joint and to improve the appearance.

A less common type of shoe is known as the one-piece or whole quarter shoe, which, as the name implies, has the rear quarter made from a single piece of leather. One method of constructing such a quarter has been to form the part by crimping in a machine with special jaws and blade, after which the parts are trimmed or cut over and finally assembled with the rest of the shoe.

It is an object of the present invention to pro;

vide a novel one-piece quarter forming machine which eliminates the necessity for crimping and cutting over. Y

It is another object of the present invention to provide a novel one-piece quarter forming vmachine which does not make deleterious rubbing or frictional contactwith the leather.

It is another object of the invention'to provide a novel machine for shaping one-piece rear shoe quarters, either before or after being attached to other parts of the shoe.

It is another object of the invention to provide a novel machine for shaping one-piece rear shoe quarters without wrinkling, bunching or creasing the leather. l

It is another object of the invention to provide a manually operable Amechanism for effecting a desired action in a one-piece quarter forming machine.

Other objjects and advantages will be obvious from the following description taken with the 5 accompanying drawings, in which? Fig. 1 is a fragmentary front elevational View of a plurality of one-piece quarter forming machines mounted on a single frame, each machine embodying the 'teachings of the present invention;

Fig. 2 is a side elevational view of the setup ,of Fig. 1 with the mounting frame shown in section; Fig. 3 is an enlarged, fragmentary, front elevational view showing the principal forming elements of the machine;

Fig. 4 is an enlarged, fragmentary, side elevational view showing the principal forming ele- K ments of the machine;

Fig. 5 is a further enlarged, side elevationall view of a shoe supporting form; Y

Fig. 6 is a vertical, sectional, elevational view taken generally along the line 6-6 of Fig. 5;. ,Y Fig. '7 is a side view of an assembled shoe having a one-piece rear quarter prior to the quarter being formed;

Fig. 8 is a fragmentary view showing the shoe of Fig. 7 mounted for forming of theone-piece quarter in accordance with the teachings of the -presepi; invention;

Fig. 9 is a side View of the shoe of Fig. 7 after the forming operation;

Fig. lois a further enlarged front elevational View similar to Fig. 3;` Figjllv is a further enlarged side elevational View similar to Fig. 4; and

Fig. 12 is a horizontal sectional view taken generally along the line |2-l2 of Fig. 11.

Referring to the drawings more particularly by reference numerals, l5 indicates generally a quarter forming machine constructed in accordance with the teachings of the present invention. The quarter forming machine I5 includes a quarter forming device I 6 and an operating mechanism l1. A plurality of machines l5 are illustrated mounted on a single angle iron supporting frame I8.

The forming device I6 includes a Vshoe sup-v .-porting form 2E! of appropriate shape as indicated in Figs. 5 and 6. This form 20 is preferablyv of cast iron with a nickel plated exterior` finish and is adapted to be heated by an electrical resistance element 2| (Figs. 4 and 8) inserted into a longitudinal bore 22. A thermostatic bulb element 23 is similarly received in a second longithe form 20 by a screw |08 as best shown in Fig. 6 The angle 101 constitutes an abutment against which the edge of the quarter may be placed to insure correct positioning on the form 20.

It has been found particularly eiiicient to form one-piece shoe quarters in two operations, the first being performed on the quarter alone and the second being performed just prior to nal finishing after the shoe is completely assembled. Obviously, the machine I is adapted to perform both operations, the forms 20, including the proper knob 106 or angle |01 and the saddles 5E, however, being different for the two operations.

It is obvious that there has been described a machine and method for forming one-piece rear quarters for shoes which attains the objects and advantages sought therefor.

It is to be understood that the foregoing description and the accompanying drawings have been given by way of illustration and example. It is also to be understood that changes in form of the several parts, substitution of equivalent elements or steps, and rearrangement of parts or steps which will be readily apparent to one skilled in the art are contemplated as within the scope of the present invention which is limited only by the claims which follow.

What is claimed is:

1. In a machine for shaping one-piece rear shoe quarters, a forming device comprising, in combination, a heated stationary form to receive a rear shoe quarter, a flexible form to cooperate with said stationary form to eifect a permanent change in the shape of a rear shoe quarter mounted therebetween, said neXibl-e form being of non-metallic construction, and manually operable reciprocable means connected to opposite ends of said flexible form for imparting a wrapping motion thereto only when a central portion thereof is restrained from translatory movement.

2. In a machine for shaping one-piece rear shoe quarters, a forming device comprising, in combination, a heated stationary form to receive a rear shoe quarter, a ilexible form to cooperate with said stationtary form to eiect a permanent change in the shape of a rear shoe quarter mounted therebetween, said ilexible form being of non-metallic construction, and a manually operable reciprocable spring-biased system of links connected to opposite ends of said iiexible form for imparting a wrapping motion thereto only when a central portion thereof is restrained from translatory movement.

3. In a machine for shaping one-piece rear shoe quarters, a forming device comprising, in combination, a heated stationary form to receive a rear shoe quarter, a yoke disposed above said stationary form and mounted for vertical reciprocation, a pair of links pivotally mounted to said yoke for oscillatory movement, a spring connected between said links for biasing the oscillatory movement thereof, means to adjust the extent of said oscillatory movement, and a eXible form of non-metallic construction connected between said links so as to straddle said stationary form, said links and said flexible form being adapted to move downwardly lduring an initial downward movement of said yoke without relative movement therebetween until a portion of said flexible form is restrained by engagement with a rear shoe quarter disposed on said stationary form, said links and said ilexible form being adapted to move relative to one another during a subsequent downward movement of said yoke, said relative movement being against the biasing action of said spring, and comprising a wrapping motion of said flexible form, whereby said flexible form may cooperate with said stationary form to eiect a permanent change in the shape of a rear shoe quarter mounted therebetween.

4. In a machine for shaping one-piece rear shoe quarters, in combination, a forming device including a reciprocable member, and a manually operable mechanism to impart a reciprocating motion to said reciprocable member comprising a foot treadle, a resilient connection between said treadle and said reciprocable member whereby a downward movement of said treadle may exert a downward pull of limited force on said reciprocable member, means to latch said treadle in a downward position and a counterweight connected to said connection between said treadle and said reciprocable member adapted to exert an upward push on said reciproca-ble member upon release of said treadle.

5. In a machine for shaping one-piece rear shoe quarters, in combination, a supporting frame, a forming device including a reciprocable member mounted at a top level of said frame, and a manually operable mechanism for reciprocating said reciprocable member comprising an adjustable link pivotally connected to said reciprocable member, a lever mounted at an intermediate level of said frame and pivotally connected to said adjustable link, a counterweight adjustably mounted on said lever so as to bias said adjustable link upwardly, a foot treadle mounted at a lower level of said frame, a link assembly connected between said adjustable link and said treadle, said link assembly including a compression spring and opposed stirrups extending therethrough, said treadle being adapted to act through said link assembly so as to exert a downward pull on said adjustable link against the biasing action of said c-ounterweight, and means for latching said treadle in a downward position so as to maintain said downward pull without attention from an operator.
